What else can I help you with?
Does the cristae increase or decrease the surface area of the inner membrane?
Cristae increases the surface area of the interior membrane of the mitocondria.
What happens if the surface area of the respiratory membrane decrease in gas exchange?
A decrease in the surface area of the respiratory membrane will result in a decrease in gas exchange.
How does the villi help the small intestine to absorb sugars quickly?
Surface Area and DiffusionThe small intestine is all about maximizing surface area. The immense amount of folding enables it to be very long meaning more surface area. The villi further increases surface area. They are projections that provide even more membrane surface area that food, while passing through the small intestine, will come in contact with. This contact with the membrane of the small intestine is how absorption occurs. Nutrients that are used in the body will diffuse across the intestinal membrane into the blood stream because the concentration will be high inside the intestine and low in the blood plasma. This difference in concentration is what "drives" diffusion across the membrane.
What cell increases the membrane surface area?
microvilli
Which membrane is adapted for absorbtion and secretion?
The gastrointestinal (GI) mucosa is adapted for absorption and secretion due to its large surface area lined with specialized cells like enterocytes, goblet cells, and enteroendocrine cells. These cells facilitate the absorption of nutrients and water while secreting enzymes, mucus, and hormones for digestive processes.
What are folds of the cell membrane on the free surface?
The folds on the free surface of a cell membrane are called microvilli. They increase the surface area of the cell membrane, allowing for greater absorption of nutrients and molecules. Microvilli are commonly found in cells that are involved in absorption, such as in the lining of the small intestine.
What is the purpose of the folded layers of membrane?
To increase the surface area.
Which membrane would have more surface area?
can someone answer the question
What makes up the surface area of a cell?
The cell membrane.
How does the folded membrane absorb the maximum amount of food needed?
A folded membrane increases the surface area available for absorption. More surface area allows for more sites for passive transport.
Why the inner membrane has many folds?
This greatly increases the surface area of the membrane so that carbohydrates (simple sugars) can combine with oxygen to produce ATP.
What is cell volume?
The volume is how much space is inside the cell. The ratio is the surface area divided by the volume. This indicates how much surface area is available compared to how big the cell is.
